Cooling device of print head in 3D printer

Abstract

The invention relates to a cooling device of print head in 3D printer, including a print head, the print head is set through a slider of the 3D printer by earrings and sliding axially, the cooling device is integrated in the print head. The internal of the housing cavity of print head is provided with a wire transporting mechanism, the axial direction of one side of the housing cavity have set up a cooling fan which is aim at the wire transporting mechanism. The lower part of the housing cavity is provided with a nozzle of the print head, and there is a wind pipe setting into the housing cavity and interconnecting to the nozzles of the print head. The present invention improves the head dissipation of the print head in 3D printer, makes the work space further reduced, and help to improve the portability of the 3D printer.

Description

TECHNICAL FIELD[0001]The invention relates to the field of the printer, especially relates to a cooling device of print head in 3D printer.TECHNICAL BACKGROUND OF THE INVENTION[0002]3D printer is a print appliance to transfer three-dimensional design computer model data into solid models currently, the fused deposition modeling technology is the mainstream 3D printer print technology that the precision of molding except by the impact of driving accuracy, but also to some extent by the precision of feeding, As the nozzle of the print head from the feeding cavity of the print head is so close that the high temperature easily spread the outside of the housing through the housing cavity of the print head when the material melting. If the temperature of housing cavity of the print head is too high, the printed material locating on the feeding portion of the print head will begin to soften, so feeding accuracy is affected thereby affecting the printer's molding accuracy, and if printed ma...

AI Technical Summary

Benefits of technology

The invention provides a cooling device for the print head of a 3D printer. The purpose is to improve cooling efficiency while reducing the space occupied by the print head.

Problems solved by technology

If the temperature of housing cavity of the print head is too high, the printed material locating on the feeding portion of the print head will begin to soften, so feeding accuracy is affected thereby affecting the printer's molding accuracy, and if printed material due to the high temperature come into melting in the feeding portion of the print head, the material melted easily plug the print head bringing about the printer malfunction.

CN203651217U discloses an Multi-field cooling device of 3D printer, the housing of print head is by a fan for cooling, but this way only for cooling the outer surface of the print head, airflow is not formed inside the housing cavity of the print head, when the wall of the print head housing is thick, easy to make the print head housing inside and outside uneven heating, inside of the print head may lead to be overheating.
